ABRAHAM YOST, OF NEW YORK, N. Y.

REFRIGERATOR.

Specification of Letters Patent No. 28,803, dated April 26, 1859.

To all whom t may concern:

Be it known that I, ABRAHAM Yos'r, of city, county, and State of NewYork, have invented certain Improvements in Refrigerators; and I dohereby declare that the following is a full, clear, and exactdescriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

Figure l represents a vertical section of the refrigerator taken throughthe red line z, s of Fig. 3. Fig. 2 is a horizontal section takenthrough the red line y, y of Fig. l. Fig. 3 shows a transverse sectiontaken through the red line of Fig. 1 in the direction of the arrows.

The nature of my invention consists in in closing the ice within a tightmetallic box and introducing the external air in immediate contact withthe outside of this receptacle and circulating the same around the icebox and from thence throughout the entire refrigerator and allowing therareed air to pass out on either side near the top of the same, throughtubes and escapes hereinafter described. Also in the peculiararrangement of pipes compartments and dampers, so that the communicationof either or all may be shut olf from the cold currents of air therebyproducing a great economy of ice.

I am aware that various devices have been essayed for producing arefrigeration, rotation and desiccation of the air within refrigeratorsand that the air has been introduced externally and brought in immediatecontact with the ice and passed down and circulated throughout therefrigerating compartments and passed out near the top of the same, butthey are all objectionable on account of their enormous consumption ofice.

It will be readily seen that in my refrigerator the warm air as itenters comes in contact with a large surface of cold metal whichinstantly lowers the temperature without exposing the ice in contactwith the air, it then falls down and circulates among the articles to berefrigerated and as the temperature is'raised it passes out throughescapes without again being submitted to the cooler or ice box,described, represented and specified as follows.

The outer casing A is constructed of nonconducting material as is commonwith most refrigerators; within this box and near its top is arrangedthe ice holder B which is made of zinc or other suitable metal;surrounding this boX are spaces C, C' which separate the ice holder fromcompartments D, D' by metal partitions 0;, provided with dampers Z), b',near their bottoms. Underneath of the ice box is arranged the drip .pansE E' constructed of semicylindrical plates which break joints so thatthe downward current of air can freely pass through the pans while thewater is conducted olf to pans G, Gr', and down through waste pipes H,H', which are placed on either side of a partition I and terminate in a'cup it which is kept full of water. and prevents the air from passingup the tubes, at the same time allowing the waste water from the ice toescape. Below the drippans F, F', are dampers J, J', for shutting olfthe communication with the compart ments K, K. L, L', are tubes whichare situated in the four corners of the compartments D, D', and openinto the compartments K, K', and convey off the air through apertures C,C' in the sides of the refrigerator. The air is conveyed off from thecompartments D, D', through apertures al, d'. N is a reservoir for waterwhich is kept cool by the ice in box B and drawn oif through faucet e.

The operation of this refrigerator is as follows: The ice holder beingfilled with ice and the covers closed tight the external air rushes inthrough aperture f and around the passages C, C in the direction of thearrows, and when the dampers are all open it circulates through thecompartments, D, D' and out through apertures CZ, d" also down throughthe drip-pans E, E', into the compartments K, K', and out through pipesL, L'. Then the dampers communicating with one or two apartments areclosed the cold air then circulates through those that are open, thusemploying only that part of the refrigerator, containing the articles tobe refrigerated, and in this manner creating a great economy of ice.

That I claim and desire to secure by Letters Patent is The combinationand arrangement of compartments D and K, dampers Z) and J and escapetubes L substantially as and for the purposes herein above set forth.

ABRAHAM YOST.
